【摘要】：為保護(hù)干旱半干旱礦區(qū)含水層及生態(tài)系統(tǒng),通過闡述榆神礦區(qū)礦床地質(zhì)、開采條件、巖層移動(dòng)特征等,從系統(tǒng)論角度提出了保水采煤的概念和科學(xué)內(nèi)涵,并構(gòu)建了保水采煤研究基本框架。認(rèn)為保水采煤適用于干旱半干旱缺水礦區(qū),目標(biāo)是保護(hù)含水層結(jié)構(gòu)和河流基流量基本穩(wěn)定;主要研究地質(zhì)條件、巖層移動(dòng)控制技術(shù)、水與生態(tài)約束條件和保水采煤關(guān)鍵技術(shù);技術(shù)途徑包括控制巖層移動(dòng)抑制導(dǎo)水裂隙帶發(fā)育、隔水層再造和注漿改造隔水層等。低成本充填技術(shù)和沙漠區(qū)地下水位相對(duì)變淺后的環(huán)境效應(yīng)是保水采煤研究面臨的挑戰(zhàn)。保水采煤研究是我國干旱半干旱礦區(qū)煤炭開采與水資源保護(hù)的理論基礎(chǔ)和依據(jù)。
[Abstract]:In order to protect the aquifer and ecosystem in arid and semi-arid mining area, the concept and scientific connotation of water-preserving coal mining are put forward from the point of view of system theory by expounding the geology, mining conditions and the characteristics of strata movement of Yushen mining area. The basic research framework of water-retaining coal mining is constructed. It is considered that water-retaining coal mining is suitable for arid and semi-arid mining areas with the aim of protecting aquifer structure and basic fluvial flow stability, mainly studying geological conditions and rock layer movement control technology. Water and ecological constraints and key technologies for water-retaining coal mining include controlling the movement of rock layers and restraining the development of water-conducting fracture zones. The low cost filling technology and the environmental effect after the relative shallowness of groundwater level in desert area are the challenges for the research of water-retaining coal mining. The research of water-retaining coal mining is a kind of coal in arid and semi-arid mining areas in China. The theoretical basis and basis of carbon mining and water resources protection.
